摘要
物体的光学信息除了常见的光谱信息还包括偏振信息。对偏振信息的采集能够实现复杂背景下对特定目标的信息提取,特别是金属目标的信息提取。结合偏振成像的原理、组成和特点,采用共孔径共探测器长波红外偏振成像系统对目标信息进行提取,通过仿真软件进行分析,系统可探测到3km远的车辆目标,且成像质量良好。
The optical information of object includes the polarization information in addition to the common spectral information.The acquisition of polarization information can achieve information extraction for a specific target in a complex background,especially the extraction of metal target information.Combined with the principle,composition and characteristics of polarization imaging,a common-aperture common-detector long-wave infrared polarization imaging system was used to extract the target information.Through simulation software analysis,the system can detect a vehicle target of 3 km away,and the imaging quality is good.
